Rotating particles using electric fields offers a platform to induce dynamic colors for display applications. We explore the rotational behavior of Janus structures comprising a metal and a dielectric material with different geometries, including matchstick-like and snowman-like configurations. We combine numerical analysis with experimental validation to gain insights into their dynamics. We investigate how different particle geometries influence rotational behavior under an applied electric field and highlight the role of high frequencies on the angular velocity and electric torque showing promise for controlling particle asymmetry for displays.
